A couple questions.

1. The help for figure says that the dpi argument
determines the "resolution".  Suppose I am producing
a PNG file for screen display: what am I changing
when I change the dpi argument (from the point of
view of the file, and from the point of viewer of
the person viewing the file onscreen).  More generally,
are there standard setting recommended for onscreen
PNG figure display?

2. EPS is a vector format, and the fig has a size.
What role does the dpi argument play here?
